Getting a replacement is not an option as any iPod nano battery is about 10 years old now. A sign of what will happen to all the Apple Watches out there.

I still use my iPod Shuffles a couple of days a week, so there's probably someone out there.

Every time I upgrade macOS, I'm amazed that even the ancient iPods are still supported. I bunged my launch day Shuffle (17 years old) into my new Mac over the weekend, and it works fine, still syncs, and Finder even still shows the icon for it.

Same with my also 17-year-old iPod Video. Man, 17 years went by quickly.
